Material Description:


  • Automotive applications
  • Many cooking, baking, and food storage products
  • Apparel including undergarments, sportswear, and footwear
  • Electronics equipment
  • Home repair and hardware
  • A host of unseen applications.

Silicone’s temperature tolerance maintains a lack of brittleness below freezing and excellent tolerance of temperatures in excess of 150 °C (302 °F).


Silicone o rings, gaskets and seals are Resistant To:  High/Dry Heat, Fungus, Sunlight, Ozone, and Weathering.


Do not use with: Fuels, silicone, and petroleum based oils, acids

Temperature Range: -75-/+450F / -59.5 -/+232C

Standard Hardness: 70 durometer Shore A

Hardness Range: 30 - 80 Durometer Shore A   

Standard Colors:    Rust/ Orange. 

Also available in Translucent.  Custom colors also available.

Trade Names:

  • Elastosil . . . Wacker
  • Silastic . . . Dow Corning
  • Silplus . . . Momentive Performance Materials

ASTM D1418 Designation: MQ, PMQ, VMQ, PVMQ

ASTM D2000/SAE J200 Type, Class: FC, FE, GE

Apple Compound Designation: SL

Standard Color: Red


Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.

Temperature Range:
Standard Compound: -40° to +220°C

Hardness (Shore A): 10 to 85

Features: Phenyl (PVMQ) based silicones can perform to -85°F. New polymers can take short term to 600°F.

Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK or concentrated acids.



Test Requested:As specified by clients,to determine total extractive residues from Rubber articles intended for repeated use in contact with food for compliance with Food and Drug Administration Regulations.

Test Method:With reference to US FDA 21 CFR 177.2600.

Simulant Used Time Temperature Max.Permissible Limit Result of 001 Comment
Distilled water 7.0hr(s) Reflux temperature 20mg/ <0.5mg/ PASS
